Programmers spend considerable time navigating source code, and we recently proposed the Patchworks code editor to help address this problem. A prior preliminary study of Patchworks found that it significantly reduced programmer navigation time and navigation errors. In this paper, we expand on these findings by investigating the effect of various patch-arranging strategies in Patchworks. To evaluate these strategies, we ran a simulation study based on actual programmer navigation data. Our simulator results showed (1) that none of the strategies tested had a significant effect on programmer-navigation time, and (2) that navigating code using Patchworks, regardless of strategy, was significantly faster than using Eclipse.

At the moment, we find that tourists usually spend more time planning their trip because they need to spend every minute. In this context, this application aims to identify the main computer needs to support the improvement of the tourist promotion point, using the mobile application proposal. Currently, for regular tourists and travelers they spend a lot of time planning and deciding on their trip to achieve maximum satisfaction. In this case, the app aims to identify the main computer needs to support the development of the tourist promotion point. This paper suggests a model for use in an intelligent visitor information system. It uses the concept of knowledge-base. The model will be based on a study of human behavior as a tourism guide. It builds a relationship between an information-based system and a guide, to provide a service to any visitor who meets their needs and the purpose of obtaining location information. There are different modules, different methods of acquisition methods and a shorter way to acquire the ingenuity of the artificial intelligence in this thesis. The proposed system should be designed in such a way that it works on most devices namely palmtop and mobiles. So it can be helpful when visiting new places. This application will find the route using user terms. The short-term method of finding an algorithm should work well and in the right way in most cases. The system must find a method that fulfills the user's terms, indicating the name of the item, images related to a brief description of the location. It should also be able to find the distance, time and travel costs to your destination and over time the user can also make bookings using the app interface only.
